4. Passage Twenty-SixToday just as technology changed the face of industry， farmers have undergone an “agricultural revolution”.On the farm of today， machines provide all the power.One of the most important benefits will be the farm computer.A few forward-looking farmers are already using computers to help them run their farms more efficiently.The computers help them keep more accurate records， so they can make better decisions on what crops to plant， how much livestock to buy， when to sell their products， and how much profit they can expect.Many computer companies have been developing special computer programs just for farmers.Programs are being written for hog (猪)producers， grain farmers， potato farmers， and dairy farmers.In the future， farmers will be able to purchase computer programs made to their needs.Because of the growing importance of computers on the farm， students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses.There can be no doubt that farmers will rely on computers even more in the future.While the old-time farm depended on horse power， and modern farms depend on machine power， farms of the future will depend on computer power.Another technological advance which is still in the experimental stage is the robot， a real “mechanized hired hand” that will be able to move and， in some ways， think like a human being.Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century.Unlike farmers of the present， farmers of the future will find that many day-to-day tasks will be done for them.Scientists are now developing robots that will be able to shear (修剪)sheep， drive tractors， and harvest fruit.Even complex jobs will be done by robots.For example， in order to milk their cows， farmers must first drive them into the special barn (畜棚)， then connect them to the milking machines， watch the machines， and disconnect them when they are finished.In the future， this will all be done by robots.In addition， when the milking is completed， the robots will automatically check to make sure that the milk is pure.The complete mobilization of the farm is far in the future， but engineers expect that some robots will be used before long.According to the engineers， ()will be done by robots in the near future.

1. Passage Twenty-ThreeWashington Irving was America’s first man of letters to be known internationally.His works were received enthusiastically both in England and in the United States.He was， in fact， one of the most successful writers of his time in the country， and at the same time winning the admiration of fellow writers like Scott in Britain and Poe and Hawthorne in the United States.The respect in which he was held was partly owing to the man himself， with his warm friendliness， his good sense， his urbanity， his gay spirits， his artistic integrity， his love of both the Old World and the New.Thackery described Irving as “a gentleman， who， though himself born in no very high sphere， was most finished， polished， witty; socially the equal of the most refined Europeans.” In England he was granted an honorary degree from Oxford—an unusual honor for a citizen of a young， uncultured nation—and he received the medal of the Royal Society of Literature.America made him ambassador to Spain.Irving’s background provides little to explain his literary achievements.A gifted but delicate child， he had little schooling.He studied law， but without zeal， and never did practice seriously.He was immune to his strict Presbyterian home environment， frequenting both social gatherings and the theatre.The main point of the first paragraph is that Washington Irving was ().

36. Questions 36 to 40 are based on the following passage.Most of us in the entrepreneurial community are blessed — or cursed — with higher-than-average ambition.Ambitious people strongly desire accomplishments and are willing to take more risks and spend more effort to get them.Overall， this is a positive quality， especially for people trying to build their own businesses.Apparently， if you’re more naturally driven to set goals， you are more likely to succeed.Actually， this isn’t always the case.In fact， in some cases， extreme ambition may end up doing more harm than good.One major side effect of excessive ambition is the tendency to focus too determinedly on one particular vision or end goal.This is problematic because it hinders your ability to adapt to new circumstances， which is vital if you want to be a successful entrepreneur.If a new competitor emerges to threaten your business， you may need to change direction， even if that means straying from your original vision.If you have too much ambition， you’ll find this hard， if not impossible.Few people are successful when they try to build their first brand.Unfortunately， for the most ambitious entrepreneurs， a failure is seen as disastrous， and impossible to recover from.It’s a clear departure from the intended plan toward the intended goal.For people with limited ambition， however， failure is viewed as something closer to reality.Remember， failure is inevitable， and every failure you survive is a learning experience.Ambitious people tend to be more materialistically successful than their non-ambitious counterparts.However， they’re only slightly happier than their less-ambitious counterparts， and tend to live significantly shorter lives.This implies that even though ambitious people are more likely to achieve conventional “success，” such success means nothing for their health and happiness—and if you don’t have health and happiness， what else could possibly matter?Clearly， some amount of ambition is good for your motivation.Without any ambition， you wouldn＇t start your own business， set or achieve goals and get far in life.But an excess of ambition can also be dangerous， putting you at risk of burnout， stubbornness and even a shorter life.What does the author think of most entrepreneurs?

A. 　They are more willing to risk their own lives.

B. 　They are more ambitious than ordinary people.

C. 　They achieve greater nonconventional success.

D. 　They have more positive qualities than most of us.

4. Passage Thirty-TwoHave you ever heard of a pawpaw (木瓜)? If not， do not feel bad.Many Americans do not know of the fruit， although it is native to the U.S.Once， however， it was one of the most popular fruits in North America.Happily， those who love the pawpaw are trying to return it to its former position in American foods.A pawpaw is a tropical fruit that used to be grown along the East Coast from New York to Florida and all over the eastern U.S.At one time， it could be found as far west as Nebraska.The pawpaw was an important food for Native Americans and even early European settlers.Pawpaws reportedly were a favorite treat of George Washington， the first U.S.president， who especially liked them cold.Thomas Jefferson， the third U.S.president， was also a fan of the fruit.He planted pawpaws at his home in Virginia.He also sent pawpaw seeds to his friends in France.American explorers Lewis and Clark wrote in their journals about the pawpaw.The pawpaw is difficult to be sold commercially.The fruit requires a very special environment—low， wet areas that sometimes flood.It has a very short harvest season， from two to three weeks in September and October.In addition， the fruit is good to eat for only two to three days after harvesting.This makes it hard to sell anywhere distant from the pawpaw tree it comes from.Planters are again growing pawpaw trees and harvesting the fruit.In several states farmers have organized “pawpaw festivals” to reintroduce people to food.At such a festival in Maryland recently， farmers displayed different products made with pawpaws， like pawpaw jams， pies， ice-cream and beer.It is difficult to sell the pawpaw on a large scale for the following reasons EXCEPT that the fruit ().
